15 Claims.

This invention relates to phonograph record shaving machines, and moreparticularly to the provision of new and improved means in such machinesfor facilitating their use.

Phonograph record shaving machines are used to obliterate therecordations made on wax-like records, to prepare the records for reuse,by the process of shaving off the surface layer of the record bearingthe recordation. This shaving operation involves rotating the record tobe resurfaced, and concurrently and progressively moving a cutting orresurfacing tool, which has been set into contact with the record, alongthe surface of the record. As the tool is so moved there are cut fromthe record long shavings or shreds of a thread-like character which aredirected, as by a chute, from the cutting tool into a collecting chamberor container. In this container the shavings usually accumulate in theform of a loose random mass. Because of the loose and random characterof this formation of the shavings, the effective capacity of thecontainer is greatly reduced.

It is an object of my invention to effectively increase the capacity ofthe container for the record shavings by controlling the character ofthe formation of the shavings in the container. One aspect of myinventionis in the provision of means to break up the record shavingsbefore 30 they enter the container; another aspect is in the provisionof means to distribute or to level the shavings within the container,

It is another object of my invention to provide means for breaking upthe record shavings which is controllable for maximum effectiveness atany given ambient temperature with a given kind of record material.

It is another object of my invention to provide a means for breaking anddistributing the record 40 shavings, which is automatically andintermittently operated during the use of the machine.

Another object of my invention is to cause the distributing means to beoperated in predetermined relation to the operation of the machine. Afeature of my invention is to provide means to cause the distributingmeans to be operated during each operation of shavinga record.

It is a further object of my invention to pro- .ao vide an improvedadjusting means, and indicating means therefor, for controlling thedepth of out, or thickness of shave, from the record.

Other and allied objects will more fully appear from the followingdescription and the appended claims.

Reference being had to Figures 1 and 2, there will be seen an upperportion of a cabinet I carrying at the top thereof a phonograph recordshaving machine. This machine has a frame or base plate 2 which supportsfor rotation a mandrel 3 adapted to carry a cylindrical record 4 to beresurfaced, The mandrel 3 is provided with a shaft 5 which is supportedat its left and right ends by a pair of thrust bearings 6 and lrespectively carried by the base plate through a standard 8 and anendgate 9. This endgate is pivoted on the base plate (as at H1) and isreleasably held in a closed position by an endgate bolt or latch H whichis pivoted (as at l2) to the right end of a guide rail l3 extendingalong the mandrel forwardly thereof. With this arrangement the bearing 1may be moved free of the right end of the mandrel by an opening of theendgate, thereby permitting a record to be mounted on, and removed from,the mandrel. When the endgate is open the shaft 5 is inter mediatelysupported by a standard [4, through which the shaft freely passes, andis retained in engagement with the thrust bearing6 by the abutment of acollar l5 on the shaft 5 against the left side of the standard l4.

The removal of a record from the mandrel is performed by a recordejector comprising a member IS in the form of a bell crank, having aleftwardly extending handle I! and an upright arm [8 carrying a shoe 19located at the left of the record. The member I6 is pivoted on a shaft20, carried at one end by the guide rail I 3 and at the other end by thestandard I 4, and is biased into inoperative position, defined by thecontact of the handle I! with the base plate, by a torsional spring 2|constrained at one end by the base plate and at the other end by thehandle I1. To operate the ejector the handle I1 is raised to move theshoe l9 into contact with the record so as to thereby push the recordfrom the mandrel.

Supported by the base plate (through the standard 8 and another standard22) is a rod 23 on which there is slidably and tiltably mounted acarriage 24 carrying a resurfacing tool 25. The carriage has a longsleeve 24' embracing the rod and an arm 26 extending forwardly over themandrel and terminating in a shoe 26 which slidably rests on the guiderail I3. The tool 25 is movably mounted on the carriage for movementtowards and away from the record. When the tool is held in operativepositiona position in which the tool engages the recorda rotation of therecord and a concurrent feeding of the carriage along the record (asfrom a start to a terminal position respectively at the right and leftends of the record) will cause a resurfacing of the record. Such feedingof the carriage is effected by a feed screw 21 rotatably supported atone end by the standard 8 and at the other end by a standard 28. Thisfeed screw is adapted to be driven coordinately with a rotation of themandrel shaft 5 by means of a belt coupling comprising a pulley 29 onthe feed screw and a pulley 30 on the mandrel shaft. The coupling of thecarriage 24 with the feed screw 21 is effected by means of a feed nut 3|carried by a resilient arm 32 extending rearwardly of the carriagesleeve 24'. When the carriage arm 26 is resting on the guide rail l3 thefeed nut 3| is urged upwardly into contact with the feed screw 21; butas the carriage arm is raised (which raising is limited by the contactof a post 33 on the carriage with a ridge 34 on the base plate) the feednut 3! is moved downwardly out of engagement with the feed screw,thereby rendering the carriage free to be manually moved along themandrel. In the use of the machine the carriage is driven or fed in aleftward direction to its terminal position and returned manually in arightward direction to its start position.

Rotation of the mandrel shaft 5 may be effect- 4 ed by a suitableelectrical motor, not herein necessary to show, which may be locatedbeneath the base plate and be coupled by a belt (not shown) to a pulley35 on the mandrel shaft, the base plate having an opening 36 throughwhich the belt may pass. Control of the motor may be effected by asuitable openable and closable switch 31, preferably of the togglevariety. This switch may be suitably located beneath the base plate inthe forward right-hand portion thereof and may be controlled by aforwardly extending control lever 38 pivoted on the base plate, thelever 38 having a shaft portion 38' extending downwardly through thebase plate. Connected by a headed screw 39 to the shaft 33' is arearwardly extending arm 40. Pivoted to the arm 40 is a slotted post 4!through which slidably passes a forwardly extending operating arm 42 ofthe switch. With this arrangement as the control lever 38 is movedleftwardly and rightwardly into on and. off positions (the off positionbeing shown in Figure 1) the switch arm 42 is moved respectivelyrightwardly and leftwardly to effect the closing and opening of theswitch 31.

The resurfacing tool 25 comprises a knife bar 43 and a knife blade 44provided at the inner end of the bar. The knife bar 43 is slidablysupported by an extension 45, provided in the right side of the carriageat a point directly above the carriage rod 23, for radial movementrelative to the record. The means for controlling the knife bar to setthe tool into operative position and to release the tool from a set oroperative position, may, in its basic arrangement, be of a constructionsuch as is disclosed in Brown Patent No. 2,137,383, issued November 22,1938 and entitled Record shaving machine. In this construction the knifebar 43 is biased away from the record, and, in the setting of the tool,is yieldably moved towards the record to bring the knife blade intoengagement therewith, the knife bar being then locked in such position.To release the tool the knife bar is merely unlocked. The means for socontrolling the tool comprises a cap 45 secured to a guide rod 41 whichpasses through the extension 45 in a direction parallel to the knifebar. The knife bar extends upwardly through the cap 46 and terminates ina head 48. When the cap is moved upwardly away from the record itcontacts the head 48 to cause the knife bar to be moved therewith. Thecap 46 is biased upwardly by a compression spring 48 coiled about theguide rod 41. By reason of this biasing of the cap the tool is normallymaintained free of the record in an inoperative position defined by thecontact of a collar 50 on the knife bar with the underside of theextension 45.

Coiled about the knife bar 43 between a collar 5| on the bar and the cap46 is a compression spring 52 which urges the knife bar downwardlyrelative to the cap into a poistion defined by the contact of the head48 with the cap. When the cap 46 is moved downwardly the knife bar isthus yieldably moved therewith, the knife blade 44 being thereby pressedinto engagement with the record. To so move the cap 46 there is provideda lever 53 which is pivoted as at 54 to the right side of the extension45. This lever is coupled by a link 55 to the cap 46, one end of thelink being pivoted by a pin 56 to a short arm 5'! of the lever 53 andthe other end of the link having a slot and screw connection 58 with theside of the cap 46. When the lever 53 is moved in a counter-clockwisedirection the cap 46 is moved downwardly to place the tool intooperative position relative to the record, the terminal movement of thelever causing a lock 59, such as is described in the above-mentionedBrown patent, to be rendered operative to hold the tool in suchposition. The terminal position of the lever 53, shown in Figure 2, isdefined by the impingement of the link against the hub 53' of the lever53. When the lever is in this terminal position, the pivot or pin 56 isslightly past dead center with respect to the pivot axes of the lever 53and of the connection 58. The lever 53 is then urged towards, andthereby releasably held in, its terminal position by the upward biasingof the cap 46. When the lever 53 is, however, tripped-i. e., movedslightly out of its terminal position to return the pin 56 across thedead center line above-mentioned-the upward biasing of the cap 46 willcause the tool to be unlocked by the clockwise turning of the lever 53from its terminal position and to be thereafter returned to inoperativeposition.

While the resurfacing tool may be manually released from operativeposition as above described, such release may be automatically effectedas an incident to the stopping of the machine by means of a mechanismsuch as is disclosed in Huenlich Patent No. 2,095,332, issued October12, 1937 and entitled Record shaving machine. This mechanism is operatedby the opening of the switch 3l-i. e., by the movement of the controllever 38 to off positionand comprises a bar 66 which extends laterallyof the machine slightly within the rear edge of a laterally extendingopening 6| provided in the base plate, the bar being supported formovement from back-tofront, and vice versa, in parallel relation to themandrel, by means of a pair of left and right links 62 and 63. Each ofthese links is pivoted to the bar at one of their ends and to suitablebosses extending down from the base plate at their other ends, such asto the boss 64 to which the link 62 is pivoted by a shoulder screw 65 asis shown in Figure 2.

The bar 66 is operatively connected with the resurfacing tool so as tocause a release of the tool from operative position whenever the bar ismoved forwardly from a resiliently biased position. The means soconnecting the bar 66 with the resurfacing tool comprises a lever 66pivoted 'on the right side of the carriage on a long shoulder screw 61,as shown in Figure 2. This lever has a lower vertical portion 68slidably contacting the front edge of the bar 66, a centralsemi-circular portion 69 curved about the carriage rod 23 rearwardlythereof and pivoted at its upper end on the shoulder screw 61 adjacentlyof the right side of the carriage, a bail portion 16 extending along thescrew 61, and a forwardly extending arm portion H pivoted on the outerend of the screw 61 and terminating at a point directly below the shortarm 51 of the tool-controlling lever 53. Thus as the bar 66 is movedforwardly the lever 66 is turned in a clockwise direction, therebycausing the arm II of the lever 66 to be moved upwardly. As the arm IIis so moved it contacts the underside of the short arm 51 of thetool-controlling lever 53 and moves the lever 53 in a clockwisedirection so as to trip the lever 53 and to thereby cause the release ofthe resurfacing tool as hereinbefore explained.

A forward movement of the bar 60, such as is required to effect therelease of the resurfacing tool is effected as an incident of moving thecontrol lever 38 to off position. The coupling of the bar 66 with thecontrol lever 38 comprises a link member 12 pivotally connected at itsrear- Ward end by a pin I3 to a rightwardly extending arm 14 of the link63 and having at its forward end portion a pin 15 which engages anarcuate slot 76 provided in a rightward extension ll of the arm 40. Inthe rearward end of the slot 16 there is provided a leftwardly extendingnotch 18. When the control lever 38 is in on position the pin 15 is heldin engagement with the notch 78 by means of a tension spring 19connected between the link member 12 and a pin 19 on the base plate andurging the link member both forwardly and leftwardly, the bar 66 beingthereby urged rearwardly into a postion defined by the contact of a stoplug 63' on the link 63 with the rearward edge of the bar 66. Thus when lthe control lever 38 is moved to off position the link member 12 ismoved rearwardly by reason of the engagement of the pin '85 with thenotch 18, the bar 60 being thereby moved forwardly to effect the releaseof the tool. This release of the tool is effected before the controllever 38 has reached its off position; subsequent to this tool release aforward end portion 12 of the link member 12 is caused to impingeagainst a boss 80 (through which passes the shaft 38' of the controllever 38) to limit the leftward movement of the link member, therebycausing during the terminal movement of the control lever 33 to offposition a movement of the pin 15 out of the notch 18. When the pin 15is rendered free of the notch 13 the link member 52 is moved forwardlyby the spring 19, the pin 15 moving forwardly along the slot 16 and thebar 60 moving rearwardly until limited by the stop lug 63'.

With the arrangement just described it is seen that the bar 60 istemporarily moved forwardly from its rearwardly biased position by themovement of the control lever 38 to off position, but that the bar 66 isnot moved from such biased position by the movement of the control lever38 to on position, the pin 15 merely sliding rearwardly relative to theslot 16 and coming to rest in the notch 18 by the movement of the lever38 to on position. Thus the resurfacing tool is released by the stoppingof the machine but is not disturbed in its setting by the starting ofthe machine.

During a shaving operation the record shavings are directed away fromthe record, by a chute 8| carried by the tool, downwardly through theopening 6! in the base plate. From the opening 6| the record shavingsare further directed downwardly into a container 82 (see Figure 2) bymeans of a chute 33 carried by the base plate and extending from alongthe front portion of the opening 6i into a throat portion 84 of thecontainer 82. The container 82 has for its sides the side walls of thecabinet I and is closed at the top, except for the throat 3t, by a plate85. The throat is formed by means of vertically extending leftand rightwalls 36 and 31, a vertically extending forward wall 88, and an inclinedrearward wall 89.

The above described structure and mechanism are common to record shavingmachines heretofore manufactured and used, and form a part of thepresent invention only in so far as they are related to or combined withother mechanism hereinafter described.

As the record shavings flow into the container 82 from the chute 8| theyform a loose random mass in the container which soon builds up into thethroat portion '84. In order to efiectively increase the capacity of thecontainer I subject the record shavings in the container to a co'mpacting and distributing action. In accordance with my invention such,efiective increase in the capacity of the container is very simplyaccomplished by the provision of simple means for distributing orleveling and also for breaking up the record shavings which accumulatein the container. While the effective capacity of the container may besubstantially increased by subjecting the record shavings to either adistributing or breaking action, I preferably employ both such actions.As shown in Figures 1, 2, 3, 4, 5 and 6, this distributing and breakingmeans is disposed along the upper portion of the container within andalong the throat portion 84, and comprises a vane 99 of rectangularshape carried along its longitudinal axis by a shaft 9|. The shaft 9I ispivoted at its left and right ends to the respective side walls 86 and81 of the throat portion 84 and is restricted against longitudinalmovement by a stop collar 92 on the right end of the shaft and by thehub 93' of an arm 93 on the left end of the shaft, as is shown in Figure4. The vane 99 is preferably open along its central portion and maysuitably comprise a pair of formed rods 99' and 99" secured as by apress fit or by riveting to the shaft 9 I.

With the above arrangement it is seen that a turning of the vane 90throughsubstantially 90 in a clockwise direction from the position itoccupies in Figure 2 will cause the record shavings as they flow fromthe chute 83 to be broken and also to be distributed in the container82. While I contemplate a recurring or intermittent operation of thevane 99 during the use of the machine, this recurring operation need notnecessarily be continuous but may be controlled in predeterminedrelation to the operation of the machine so as to cause a reciprocationof the vane during each record shaving operation. There are many partsof the machine which are cyclically operated or manipulated during eachoperation of shaving a record. In accordance with my invention the vanemay be suitably operated by, or coincidentally with, any one of suchcyclically operated parts.

In the embodiment of my invention as illustrated in Figures 1, 2, 3 and4, the vane is electromagnetically operated and controlled by the recordejector I6. Reference being had particularly to Figures 2 and 4 therewill be seen an iron-clad solenoid 94 secured by screws 95 to the topplate 85 of the container 82 and having a plunger 96 connected by a link91 to the arm 93 on the shaft 9|, the link being pivotally connected tothe plunger 96 and to the arm 93 by the respective pins 98 and 99. Thevane 99 is biased into a position defined by the contact of the arm 93with a stop pin I99 on the wall 86 (the position the vane occupies inFigure 2) by means of a tension spring IIII connected between the link91 and a pin IIII' on the wall 86. When the solenoid 94 is energized theplunger 96 is propelled rearwardly to turn the vane 99 throughapproximately from its biased position, the vane being returned by thespring II'II when the solenoid is thereafter deenergized. In order thatthe solenoid 94 will be energized by the operation of the record ejectorI6 there is secured on the side of the handle II, by a clamp I92, amercury switch I03 sensitive to its positioning, which switch may beserially connected in the circuit of the solenoid 94 to cause thesolenoid to be energized when the switch is closed and deenergized whenthe switch is open The switch I93'may be of well known variety,comprising a glass bulb I94 having a pair of terminals I95 and a globuleof mercury I96. The switch is mounted in an angular position on thehandle I1 so that it will be open when the record ejector is unoperated,as shown in Figure 3, and closed when the handle I! is raised to operatethe ejector. Thus when the ejector is operated and then returned tounoperated position the vane is turned to and fro to cause both adistributing and breaking effect on the record shavings in the container82, the vane being moved in one direction by the solenoid 94 and in theother direction by the spring I9I.

InFigures 5 and 6 there is shown means by which the vane 99 is moved toand fro as an incident of moving the control lever 38 to off position tostop the machine. As hereinbefore described, the bar 69 is caused to bemoved to and fro from a rearwardly biased position by the movement ofthe control lever 38 to off position; this bar may thus very suitablyoperate the vane 99. The means for connecting the bar 69 to the vane 99comprises a lever I91 pivoted at I98 on a bracket I99 secured to the endwall 86. The lower end of the lever I91 terminates in a slot I I9 whichengages a cross pin I I I carried by the arm I93, the arm being securedto the shaft 9| at a slight angle relative to the vane, as shown inFigure 6. The upper end of the lever I91 terminates in a slot H2 whichengages a pin H3 carried by a bracket H4 secured by the pins H4 to theleft end of the bar 69. With this arrangement forward and rearwardmovements of the bar 69 cause clockwise and counter-clockwise movementsof the vane 99. Thus the vane 99 is turned to and fro by the bar 69 asthe machine is stopped; furthermore, since the resurfacing tool isreleased by the stopping of the machine the vane is moved coincidentallywith the automatic release of the tool.

In Figures 7 and 8 there is shown a modified means for breaking therecord shavings as they flow from the chute 83. This means comprises anL-shaped extension H5 secured ,by the screws H6 to the lower verticalportion 68 of the lever 66 carried by the carriage 24. The extension H5has a blade II I provided with left and right cutting edges I I1 andextending forwardly across the lower end of the chute 83. As thecarriage is moved along the mandrel the blade H1 traverses the path ofthe record shavings from the chute 83 to cause a breaking of recordshavings which may have lodged in the throat portion 84. While thisbreaking action may be mild during a record resurfacing, by reason ofthe slow rate of feed of the carriage, the breaking action will behighly accelerated during the manual return of the carriage since thecarriage return is ordinarily effected at a relatively high rate ofspeed.

In addition to the foregoing I provide a means carried by the chute illfor subjecting the record shavings to a breaking action as they passthrough this chute. The chute 8|, which is illustrated in detail inFigures 9, 10, 11 and 12, comprises a collar portion I I8 which embracesthe inner end of the knife bar 43 and which is secured to the knife barby a set screw H9. This collar portion has an open sector I 20 ofsubstantially 90 angular width and is closed at its lower and except fora slit I2I through which extends the knife blade 44 carried by the knifebar 43. Extending angularly downwardly from the collar portion H8 on theside of the open sector I29 is an outwardly flanged conduit I22,square-shaped in cross section, which terminates in the upper portion ofthe chute 83. During a record resurfacing the record shavings passthrough the slit I2I and into the conduit I22 by way of the open sectorI20. Due to the high rotational speed of the record during a recordresurfacing, the record shavings are caused to move into the conduit I22at a high rate of speed. In accordance with my invention I takeadvantage of this high rate of speed of the shavings to cause the sameto be broken up as they pass through the chute 8|. This is done byproviding, in the path of the shavings through the chute, a deflectingmeans which as the shavings impinge thereupon causes the shavings to besubjected to a bending and breaking action.

The deflecting means above mentioned is preferably made in the form of abaffle plate I23 which is movably mounted within the path of theshavings through the chute SI for angular adjustment relative to suchpath. Such movable mounting of the ballle plate I23 may be effected bypivoting the plate to the collar portion IIB, as on a rod or pin I24, sothat the plate will control the opening of the sector I20, the platebeing manually adjustable in position relative to the sector, or to thepath of the shavings through the sector, by a fingerpiece I25 providedon the side of the plate. In operation, the plate I23 is positionedangularly relative to the path of the shavings through the sector I22 sothat the shavings will impinge upon the plate and by such impingement besharply deflected, thereby subjecting the shavings to such bendingforces as will result in a breaking of the shavings. The feature ofrendering the baffle plate I23 angularly adjustable relative to the pathof the shavings is important in that it permits the operator to controlthe angle of impingement of the shavings on the plate for maximumbreaking action, the angle of impingement for maximum breaking actiondepending upon the character of the record material and the ambienttemperature during the record shaving operation.

It is an additional feature of my invention to provide an adjustablemeans, and an indicator therefor, for controlling the set position ofthe tool relative to the record and thereby the depth of cut orthickness of shaving which is taken by the tool during a recordresurfacing. This adjustable means is shown in Figures '7, 13 and 14,and comprises a bracket I26 which is carried by and within the cap 46 ofthe tool-setting means hereinbefore described. The bracket has an armI28 apertured to embrace the upper end of the knife bar 43 and issecured to the cap 46 by a pair of screws I21 which pass through anapertured plate I28 and then through a slot I29 in the side wall of thecap to thread into the bracket I26. The slot I29 extends longitudinallyof the knife bar it to permit an adjustment of the bracket I26 on thecap 46 in directions longitudinally of the bar, the plate I28 having anindicating finger I 3!] to indicate relative to a scale I3I, provided onthe side wall of the cap 46, the adjustment of the bracket I26 relativeto the cap. The spring 52, which yieldably connects the cap 46 to theknife bar 43, is disposed between the arm I26' of the bracket I25 andthe collar ill on the knife bar.

It has been seen that in a tool-setting operation the cap 46 is moved apredetermined distance towards the record, and that by such movement ofthe cap the resurfacing tool is brought into contact with the record andthe spring 52 is then compressed to urge the knife blade 44 of the toolinto the record material. The extent of the compression of the spring52, in the setting of the tool, is controlled by the thickness of therecord on the mandrel and by the adjustment of the bracket I25 relativeto the cap 66, the compression being increased as the bracket is moveddownwardly relative to the cap, the finger I30 then moving upwardly withrespect to the numerals of the scale IEI. When the compression of thespring 52 is increased the knife blade 44 is pushed further into therecord material to cause the tool to be set for deeper depths of cut.Thus the finger IBII serves to indicate relative to the scale I3I theposition in which the tool will be set relative to the record upon theoperation of the tool-setting means. This indication is veryadvantageously highly magnified since a considerable increase inpressure of the tool against the record is necessary to effect arelatively small increase in the depth with which the tool is setrelative to the record and since the pressure with which the tool isforced against the record is directly controlled by the adjustment ofthe bracket I26 relative to the cap 46.
